Is this intentional?

zsh % cat tmp.rb
module Foo
  def foo
    return __callee__
  end
end

class Bar
  include Foo
  alias bar foo
end

b = Bar.new

p b.foo
p b.bar
p(b.method(:foo) == b.method(:bar))
zsh % ruby22 -v tmp.rb
ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin15]
:foo
:bar
true
zsh % ruby23 -v tmp.rb
ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin15]
:foo
:foo
false

I think it is a bug.
